Narendra Singh Tomar, Union Minister of Rural Development, Panchayati Raj and Mines, witnessed the maximum rise in his wealth during 2015-17, while Prakash Javadekar, Minister of Human Resource Development, saw the steepest decline during the period, according to data sourced from the Prime Minister's Office website.

Interestingly, an analysis of the combined wealth of the ministers and their spouses paint a completely different picture such as in the case of Javadekar and Paswan. Prachi Javadekar's saw 190 percent increase in wealth over the two-year period. The Javadekar's jointly saw their wealth increase 107 percent, the highest among the lot, to Rs 6.69 crore.

Similar is the case with Paswan, whose wealth including that of Reena Paswan, witnessed 14.9 percent rise to Rs 1.23 crore.

Of the 14 ministers, whose wealth data for 2016-17 is available, finance minister Arun Jatiley is the wealthiest with net assets worth Rs 67.7 crore. Adding up his wife Sangita Jaitley's wealth, the net asset surged to Rs 100.97 crore. On individual basis, Birender Singh comes in at a distant second with Rs 9.85 crore. However, on a combined basis, the Swarajs ranked second with net assets of Rs 28.41 crore.
